Custom Widget disappearing when page is opened more than once

I created a custom widget with a custom function and called that function inside the update function update: function (obj, callback) { logger.debug( + ".update"); this._customTable(); this._contextObj = obj; this._updateRendering(callback); }, _customTable: function CustomFunction() { //Code var divContainer = document.getElementById("customTableWidget"); divContainer.innerHTML = ""; divContainer.appendChild(table); } And I used it in the template html <div class="widgetname" data-dojo-attach-point="widgetBase"> <body> <p id="customTableWidget"></p> </body> </div> I used the widget in a page and when I go to the page I get the output But, when I click the page button again (the Blue-White Asterisk), the table vanishes. The table comes back if I go back to Home and come back. When I search for the tag, the tag is there but the tags created by the javascript is gone. I’m new to custom widgets and I just did this with basics taught in the learning path. Please help me solve this. Is there any code placement problems or any other?

Mendix does not cope well with setting innerHTML as empty once you rerender the javascript code. Could you try setting it with a ‘space’ or even some text and checking whether it works then?

It is also best practice to create the necessary HTML elements with a widget template HTML file, with something like:

<canvas id="widgetid" class="col-md-10"  data-dojo-attach-point="yourDiv"></canvas>

 Then, in the widget JS code you can target it with:



Also, what -if any- message can you see in the browser console once the container disappears?
